Multiple myeloma is a haematological malignancy characterized by the occurrence of plasma cell tumours within the bone marrow. In advanced multiple myeloma, metastatic deposits outside the bone marrow (extramedullary) are rare. Reported extramedullary sites include the upper respiratory tract and lymph nodes. Parenchymal pulmonary plasmacytoma is exceptionally rare. We describe such a case in a 51-year-old male, who underwent allogenic marrow transplantation. 6 months post-transplantation developing nodal and hilar pulmonary multiple myeloma, the radiological appearances mimicking lymphoma.
多发性骨髓瘤是一种血液系统恶性肿瘤，其特征是骨髓内出现浆细胞瘤。在晚期多发性骨髓瘤中，骨髓外（髓外）转移灶很少见。报道的髓外部位包括上呼吸道和淋巴结。实质性肺浆细胞瘤极为罕见。我们描述了一名51岁男性的此类病例，该患者接受了异基因骨髓移植。移植后6个月出现肺门和纵隔多发骨髓瘤，影像学表现类似淋巴瘤。
